Local potentials can be either excitatory (depolarizing, like with ACh) or inhibitory (hyperpolarizing, like with glycine), altering the membrane potential towards or away from the threshold.
Some signals (<b>glycine</b>) make the membrane potential more negative (<b>hyperpolarizing</b>) while others (<b>ACh</b>) make it more positive (<b>depolarizing</b>)
